dave tinkle My apologizes for delayed response (somehow I didn't see the email notification of your reply).
Which client app did you use - is that a custom JS API app or WAB app? Either way, could you pls try with the latest version of that client app?
for custom JS API, pls update to its latest version
if it the map viewer from ArcGIS Online, then it should work as of today.
for on-premises Portal map viewer/Web App Builder, you need to upgrade to 10.6.1
Simply put, displaying "Override 1" is unacceptable, and no one appears to be motivated to explain what's gone wrong
In short, it was a side effect to work-around technical limitations with regards to color level transparency that was not supported by Windows GDI -- a print service heavily relied on GDI.
Print services, that get installed out of the box in 10.6 (or above) or when you publish your own print service from ArcGIS Pro 2.1 to ArcGIS Enterprise 10.6 (or above), don't rely on GDI at all hence you should not run into this issue.
